To achieve satisfying airspeed readings with pitot static systems during unsteady flight conditions, the static ports must be able to read free stream data. Installation of small barriers called air dams around static ports can help the system to achieve accurate airspeed readings. Different dam configurations are investigated utilizing computational fluid dynamics.
